The agitator is a typical mixing device. Stirring the material with a stirrer can achieve good mixing and uniform effect. The agitator is very common in industrial and civil fields, but the working principle and structure of the agitator are similar regardless of the application. The following are several agitators classified by structural features. Paddle stirrer: The paddle stirrer is a relatively simple agitator with two stirring blades.
The paddle agitator can be divided into a paddle type agitator and a paddle type agitator according to the shape characteristics of the blade. The flat paddle agitator produces a radial force and the pitch paddle agitator produces an axial force. The paddle stirrer is suitable for mixing low viscosity liquids, suspensions and solutions. Spindle agitator: A propeller agitator is a stirrer with two to three propellers as agitating components. The propeller type agitator has a high rotation speed when agitating, and can force the material to move in the axial direction, so that the material is fully circulated and mixed.
Propeller type agitator is more suitable for mixing liquids, suspensions, emulsions and other materials with low viscosity.
Turbo agitator: Turbo agitators are usually designed with two to four blades, which can be straight or curved and mounted on a horizontal disc. The turbine agitator creates a highly turbulent radial flow of material as it rotates. Turbine agitators are suitable for mixing gases or liquid materials that are less viscous and less miscible.
Anchor stirrer: As the name suggests, the anchor stirrer is very similar to the ship's anchor. The blade size of the anchor stirrer is similar to the size of the agitating tank, and only a small gap is left after the combination, so that the blades of the anchor stirrer can remove the reactants on the inner wall of the stirring tank while rotating, and maintain the stirrer. Stirring effect. Anchor stirrers can be used to agitate materials with higher viscosities.
Ribbon agitator: The blade of the ribbon agitator is in the form of a ribbon. The number of ribbons is two to three. It is mounted on the screw in the center of the agitator. The pitch of the ribbon agitator determines the outside of the ribbon. path. The ribbon agitator is typically operated in a laminar flow condition and is suitable for the mixing of highly viscous liquids and pseudoplastic fluids.
Magnetic stirrer: The magnetic stirrer is a kind of agitator manufactured by the principle of magnetic coupler. The magnetic stirrer is characterized by a safe and closed agitation process, avoiding the leakage problem during the agitation process and improving the working efficiency of the agitator. The magnetic stirrer can be used for the stirring of various toxic and harmful substances, especially suitable for petrochemical, organic pharmaceutical and other industries.
